Overview

Multi-channel digital video optical transceiver can transmit multi-channel high quality video, multi-channel audio or multi-channel bi-directional audio, multi-channel positive/reverse/bi-directional Asynchronous data in one fiber.

It adopts full digital uncompressed techniques, and supports high-resolution movement and still picture-undistorted transmission.

It is now widely used in security monitoring and control system, highway, Traffic Control Photographic System, automation and intelligent residence.

Character:

Industrial-level design with SMT techniques;

Full digital transmission in fiber, multi-service flexible configuration on the same platform;

Supply desktop and integrated card type;

Based on large scale integrated circuit

Transmission in single-fiber, dual-fiber is optional;

Fully compatible with PAL/NTSC/SECAM;

Support asynchronous data (positive/reverse), transmission rate is up to 115.200Kbps;

Support RS232, RS422, RS485 or Manchester code;
